When frying the meat section, we must master the fire and time. If the fire is too big, it is easy to fry the meat. If the time is too long, the meat will be dried. The taste is not good. 3. Mix 1 teaspoon vinegar, 1 teaspoon oyster sauce, 3 teaspoon tomato sauce, 4 teaspoons sugar and 1 teaspoon water to make the sweet and sour juice taste good and lustrous. 4.
